How to Trim the video

1
Add your video
MP4, MOV, MKV, WebM or AVI, up to 200 MB and five minutes. The file is read on your device and never leaves it.
2
Drag the two handles to the part you want
The timeline shows the frame under each handle, so you can see exactly where the cut lands before committing to it.
3
Click Trim and download
You get an MP4 of just that stretch, with the sound, ready to send or to hand to the next tool.

The cut lands where you put it

Most trimming tools cut on keyframes. Video is not stored frame by frame: one full picture is followed by a couple of hundred frames that only describe what changed, so a tool that copies the stream without decoding it has to start at the nearest full picture before your mark. With a typical recording that is up to ten seconds earlier than you asked. This tool decodes and re-encodes instead, which means the first frame of the result is the frame you chose and nothing else creeps in at the front. The price is that encoding takes processor time, so a two-minute clip takes tens of seconds rather than an instant, and the picture is re-compressed once. At the bitrate of the source that difference is not something you will spot on a phone or a laptop.

What it is good for

Cutting the dead air off the front of a screen recording. Pulling the ten seconds worth watching out of a two-minute clip before sending it. Getting a video under a messaging limit, since trimming removes weight far faster than compressing does, because you are removing time rather than detail. Taking the exact stretch you want to turn into a GIF or an audio file later; both of those are much less painful when the input is short. If you need the whole video but smaller, compressing is the tool for that, and the two work together: trim first, compress the result.

Sound, and the option to drop it

The soundtrack is carried across by default, cut to the same stretch as the picture, so there is no drift between them. Turning sound off makes the file meaningfully smaller and is the right choice for a silent screen capture, a background loop, or anything going into a feed that plays muted. It cannot be brought back afterwards, so the original is worth keeping until you are sure.

Why the browser and not a server

The whole job runs on your machine using the video encoder that is already built into your browser. Your file is never uploaded, there is no queue and no account, and closing the tab clears everything. It also means the limits are your machine's rather than ours: 200 MB and five minutes is where browser memory starts to be the binding constraint. A longer or heavier file is not refused quietly; the page says so and tells you what to do instead.

Cut on your device, nowhere else

Only the frames between your two points are decoded and encoded again, by the encoder built into your browser, and the MP4 is written inside this tab. There is no upload, no account and no queue, closing the tab clears everything, and you can trim as many videos as you need.

Frequently asked questions

Does the cut start exactly where I put it?

Yes. The first frame of the result is the frame under the left handle. Tools that copy the stream without re-encoding cannot promise that, because they have to start at the nearest keyframe, which can be several seconds earlier.

Does trimming lose quality?

The picture is encoded once more, at the bitrate of the source, so the loss is a single generation and generally invisible at normal viewing size. If you plan to trim, crop and compress the same video, do it in one session rather than exporting and re-importing between each step.

Can I cut a piece out of the middle?

Not yet. That means joining the two remaining halves, which is a different operation and is coming with the merge tool. For now you can trim twice and keep both pieces.

Why 200 MB and five minutes?

Because every frame is decoded and encoded in your browser's memory. Beyond that, browsers start to run out of room and would fail partway through, which is worse than being told up front.

Is the sound kept?

Yes, cut to the same range, unless you turn it off. On some browsers the soundtrack is saved as Opus rather than AAC; if that happens the page tells you, because such a file plays in Chrome, Firefox and Edge but not in QuickTime.

Is my video uploaded anywhere?

No. It is read from disk into the page, processed there, and written back out as a download. Nothing is sent to a server, and we could not see it even if we wanted to.

Does it work on a phone?

On a recent iPhone or Android phone, yes, for short clips. Phones have less memory and a slower encoder, so a long 1080p video is better handled on a laptop.

What formats can I put in?

MP4, MOV, MKV, WebM and AVI, as long as the video inside is H.264, VP8, VP9 or AV1. The result is always an MP4. HEVC from newer iPhones depends on the machine: if your browser cannot decode it, the page says so rather than producing a broken file.
